How to Make a Cardboard Windmill

Children can be fascinated by cardboard windmills. Watching the paper windmill rotate and spin is not only enjoyable, the process can be educational if you talk about how real windmills work in conjunction with how a play windmill moves. Not only is a cardboard enjoyable to play with, it can be an interesting art project as well. Learn how to make a cardboard windmill and entertain your children with this project.

Fold the square of paper in half from corner to corner diagonally. Fold it in half diagonally again to create a triangle shape. Unfold the paper and smooth it flat.

Mark a point approximately two inches from the outside edge along each fold line.

Decorate the paper square with the markers to make it colourful.

Cut along the fold lines with the scissors to the marks made in step 2. Fold every other corner down to reach the middle point of the square and overlap by a tiny bit. Crease the fold lines so the folded paper points stay folded.

Poke the point of the pencil through the centre of the paper square to make a small hole. Place the pencil aside for the next step.

Place the cardboard tube on end. Pass the pencil through one side of the tube, straight across and out the other side approximately two inches from one end of the tube. Adjust the straw so that it protrudes out approximately an inch from the tube on one side off the tube.

Use a dime-sized lump of modelling clay to hold the short end of the straw in place around the hole on the side of the cardboard tube.

Push the centre hole of the folded paper square onto the side of the straw that does not have clay on it. Spin the paper pinwheel to make sure it spins freely.
